If you've ever stared down a whole chicken in your fridge and an inbuilt BBQ in your backyard thinking, "There's no way I can pull this off without it turning into a burnt hockey puck or a raw bird in the middle," trust me-you're not alone. When I first started working with inbuilt BBQs (y'know, the kind that gets built right into your outdoor kitchen, no moving it around when the neighbors need space), I thought cooking a whole chicken would be super tricky. Spoiler: it's actually one of the easiest, juiciest, most impressive things you can make on these things. And since I'm part of a team that sells both Built in Natural Gas Barbecue and Built in Propane Grill, I've tested this recipe on every model we stock. Let's break it down like we're chatting over a beer after a long day-no fancy chef jargon, just real, doable steps.
First, let's talk basics: why an inbuilt BBQ is perfect for a whole chicken. Unlike those tiny portable grills that heat unevenly, inbuilt models have burners spaced evenly across the cooking area, and most come with a lid thermometer (game changer, I swear). No more guessing if the temp's right-this is why so many of our customers say they'd never go back to a regular grill once they've tried their first inbuilt one. The key here is indirect heat. If you crank all the burners up to high and plop the chicken right over them, the skin will char in 2 minutes flat, but the inside will still be frozen. We're going low and slow (well, not super slow, but low enough to cook through without burning) with indirect heat-this is how you get crispy skin and juicy meat.
Let's start with prep. You can't just take a chicken out of the pack and throw it on the grill, okay? A few small steps here make all the difference. First, buy a whole chicken that's 4 to 5 pounds. Anything bigger and it'll take way too long, anything smaller and the skin burns before the inside is done. Take it out of the packaging, pat it super dry with paper towels. Wet skin = no crispiness, that's a rule I live by. Dry it really well-maybe let it sit on a rack in the fridge for an hour while you prep the rest, if you have time. That extra hour makes a huge difference, I promise.
Next, seasonings. I keep this simple, no weird spices that will overwhelm the chicken. Here's what I use: 1 tablespoon of kosher salt, 1 teaspoon of black pepper, 1 teaspoon of garlic powder, 1 teaspoon of paprika (smoked if you have it, regular works too), and a tiny pinch of brown sugar (it helps the skin crisp up and get that golden color). Mix those together in a small bowl. Then, take the chicken-make sure to pull out the giblets from the cavity (those are usually in a little bag, don't forget that, I've made that mistake once and had to pick through the chicken at dinner). Pat the outside one more time, then rub the seasoning all over. Don't be shy-get under the wings and where the legs are, that's where people usually miss. Also, I like to stuff the cavity with a halved lemon and a couple of garlic cloves. It adds so much subtle flavor, and the steam from the lemon keeps the chicken moist. You can skip this if you hate lemon, but I highly recommend it.
Now, the BBQ part. This is where things get specific for inbuilt BBQs. First, decide if you're using natural gas or propane-both work great, just need to set the burners differently. If you have a Built in Natural Gas Barbecue, it heats up a little more evenly than propane, but that's barely noticeable for this recipe. For both models, we're using indirect heat. Here's how to set it up: turn on the left and right burners to medium (around 350°F, which is what the lid thermometer will tell you). Leave the middle burner off. Wait, why? Because we're not cooking the chicken directly over the flame-we're cooking it in the hot air that fills the lid, like an outdoor oven. If you have a three-burner inbuilt BBQ, that's the sweet spot. If you have a four-burner, just turn on the two outer burners and leave the two middle ones off. The point is, there's no flame under the chicken-this is how you get even cooking.
Put the chicken on the grill. I use a wire roasting rack, but if you don't have one, you can place it right on the grill grates, breast side up. Wait-should you flip it? I tried flipping it once, and half the skin stuck to the grates and fell off. Now I keep it breast side up the whole time. But here's a pro tip from our team: after about 30 minutes, you can tent a piece of aluminum foil over the breast if it starts getting too dark. Chicken breast cooks faster than the legs, so this keeps it from drying out.
Now, the waiting game. Resist the urge to keep lifting the lid! Every time you lift it, the temp drops by 25 degrees, and you add 5 minutes to the total cook time. I know it's hard, but try to only check the temp once or twice. How long does this take? About 1 hour and 15 minutes, give or take. The key is using that lid thermometer. You're looking for the thickest part of the thigh (not touching the bone) to hit 165°F. If you have a meat thermometer, that's even better-stick it in the thigh at the start, and you don't have to guess. When the chicken is almost done, turn the two burners up to medium-high (around 400°F) for the last 5 to 10 minutes. This crisps up the skin without burning it. This is where that pinch of brown sugar in the seasoning pays off-you'll get that perfect golden, crispy skin that makes everyone go "wow."
Once it's done, take it off the grill. Don't cut into it right away! Let it rest for 10 minutes. This is the most important step people skip. If you cut it immediately, all the juice runs out onto the cutting board, and the chicken is dry. Resting lets the juices redistribute into the meat. I usually set it on a cutting board, cover it loosely with foil, and go grab a soda while I wait. Perfect time to hang out and look at your inbuilt BBQ, thinking about how glad you are you didn't buy that small portable one.
Now, let's talk troubleshooting-because even after all this, things can go wrong, and I've seen it. Problem 1: Skin is not crispy. Either you didn't pat the chicken dry enough, or the heat was too low for the last part. Next time, use that foil tent only if you need it, and crank the burners at the end. Problem 2: Chicken is raw in the middle. You either lifted the lid too much, or your inbuilt BBQ runs a little hot or cold. Invest in a meat thermometer-they're like $10 and fix that every time. Problem 3: Chicken is dry. You cooked it too long, or didn't let it rest. Stick to the 1 hour 15 minute timer, and rest it, I beg you.
Wait, a quick note on inbuilt BBQ vs. regular grills-something I get asked all the time. We sell Built in Propane Grill models that are super popular, but the setup is almost identical to the natural gas ones. The only difference is propane tends to have a slightly higher heat output, so you might want to turn the burners down to medium instead of medium. But honestly, this recipe works on every inbuilt model we carry. The reason our customers love cooking whole chickens on these is that the consistent heat means you don't have to hover over it like you do with a portable grill. You can fire up the inbuilt BBQ, prep the rest of your side dishes, and come back to a perfectly cooked chicken.
What to serve with it? Roasted veggies (you can throw those on the edge of the grill while the chicken rests), a simple green salad, or some mashed potatoes. It's a weeknight win, or perfect for a small weekend cookout. I've made this for friends who thought they "didn't like grilled chicken" and now ask for it every time.

And one last pro tip for when you're done. After you're done eating, don't forget to clean your inbuilt BBQ. While it's still warm (not hot), brush the grates with a grill brush to get rid of any chicken bits. For the burners, we recommend a quick wipe down every few uses-our inbuilt models are easy to clean, so you don't have to stress about it. That way, your next whole chicken will be even better, no extra work.
Cooking a whole chicken on an inbuilt BBQ isn't as scary as it sounds. It's simple, it's juicy, it's crispy, and it's way easier than most people think. Whether you go with natural gas or propane, following these steps will give you a chicken that's the star of any meal.
